Surge arrester, 4P Type 1+2 (class B+C) type V50-4-280 5093513

Electrical installation protection with OBO V50 surge limiters

V50 series surge limiters are proven class B+C (Type 1+2) devices, combining protection against direct and indirect lightning strikes and overvoltages generated by devices. Designed for use in residential and commercial buildings, they provide comprehensive protection for electrical installations and connected devices. The construction based on hybrid technology guarantees high efficiency and durability.

Construction and application

The V50-4-280 surge limiter is a four-pole device designed for mounting on a TH-35 mm DIN rail. It provides protection in TN-S, TN-C, TN-C-S networks and protects against overvoltages in DC circuits up to 350V and AC circuits up to 280V. Its versatility makes it an ideal solution for both installers and end-users looking for reliable protection. The impulse current per pole is 12.5 kA (10/350 µs), and the L-N protection level is 1.3 kV. The maximum wire cross-section is 35 mm², allowing connection of wires of various thicknesses.

Key features and benefits

• Versatility: The limiter is suitable for different types of networks (TN-S, TN-C, TN-C-S) and DC and AC installations.
• High efficiency: Class B+C provides protection against both direct and indirect lightning strikes and overvoltages generated by devices.
• Safety: Low voltage protection level (<1.3 kV) minimizes the risk of damage to connected devices.
• Durability: Made of self-extinguishing plastic (UL 94 V-0) provides resistance to high temperatures and fire.
• Replaceable cartridge: Allows quick replacement of a damaged element without the need to disassemble the entire device. The cartridge has optical damage indication for easy identification of the need for replacement.
• Mechanical protection: The cartridge locking latch protects against the element sliding out during operation and provides anti-vibration protection of the connections.
• Halogen-free plastic: The housing made of halogen-free material minimizes the emission of toxic gases in the event of a fire, increasing the safety of users and the building structure.
• Universality for installers: No need to further secure up to 160A GL simplifies the design and installation of the electrical installation.

V50 surge limiters are an investment in the safety and reliability of the electrical installation, which translates into peace of mind for users and minimization of the risk of costly equipment failures. Thanks to advanced technology and high-quality workmanship, they are an optimal solution for demanding customers who value durability and efficiency.
